Calcium carbonate is one of the important components in the culture medium of pharmaceutical industry. It not only provides Ca element, but also buffers the change of PH in the process of stable fermentation. So calcium carbonate becomes the buffer of microbial fermentation in pharmaceutical industry. Among the reagents of drugs, calcium carbonate can generally be used as filler, while it has certain pharmacodynamic effect in acid tablets.

Calcium carbonate can be used as food additive. It is advisable to add a small amount of calcium carbonate in food, usually no more than 2%, to ensure the necessary intake of calcium. Because under normal circumstances, the total amount of calcium in human body is about 1200 grams, 99% of which is in the iliac bone and teeth, and 1% is an essential component in human blood, so calcium carbonate is one of the various food additives. In some foods (such as chewing gum and chocolate), calcium carbonate is used as a fortifier to reduce costs and as a matrix material.
